Question

A light emitting diode (LED) is fabricated using GaAs semiconducting material whose band gap is …. The wavelength of light emitted from the LED is :

Accepted Answer

Option B. The wavelength of light emitted by a Light Emitting Diode (LED) fabricated using a semiconducting material can be determined by the energy band gap of the material. The energy of the photon emitted, which corresponds to the band gap energy, is given by the equation:
